Genetic engineering has shaped science for decades in ways that often sound surprising or even strange. From glowing animals to modified foods and disease-fighting plants, these experiments show how far researchers have pushed biology. This list explores unusual examples from history that reveal both the promise and the questions behind genetic innovation.
#1: Edible Vaccines Developed in Bananas
Scientists began exploring edible vaccines in the late 20th century as an easier way to deliver immunization. By inserting harmless viral proteins into bananas, researchers created fruit that could trigger immune responses. This idea builds on traditional vaccines but removes needles, making distribution simpler, especially in developing regions with limited medical infrastructure.
